Democracy Now! has long covered the issue of climate change. We reported from the U.N. Climate Change Conferences in Warsaw, Doha, Durban, Cancún, and Copenhagen, and from the World Peoples’ Summit on Climate Change hosted by Bolivia. We’ve interviewed many of the world’s top scientists, writers, policy makers, activists, indigenous leaders and academics on the issue. We continue to follow the environmental movements to directly confront the root causes of global warming, and to advocate for climate justice, and sustainable alternatives.
